# Providers

Providers in Agent Auth represent third-party applications that your users can connect to and interact with through Scalekit's unified API. Each provider offers a set of tools and capabilities that can be executed on behalf of connected users.

## What are providers?

Providers are pre-configured integrations with popular third-party applications that enable your users to:

- **Connect their accounts** using secure authentication methods
- **Execute tools and actions** through a unified API interface
- **Access data and functionality** from external applications
- **Maintain secure connections** with proper authorization scopes
